Main Construction Method of Anchor （1） 、總體方案 Scheme錨桿施工與邊坡開(kāi)挖施工同步進(jìn)行，上層邊坡支護(hù)施工完成，開(kāi)挖至預(yù)應(yīng)力錨桿施工位置后，及時(shí)組織進(jìn)行腰梁及預(yù)應(yīng)力錨桿施工，完成邊坡防護(hù)，減少邊坡暴露時(shí)間。 2).Construction Sequence of Anchor: The anchor construction shall be conducted from the top to the bottom(some proper adjustment can be made according to the actual situation) under the principle of sequence and denseness. Grout leaking between anchor holes shall be avoided in order to prevent the serious impact on construction effect. See Attachment 1 for detailed Plan of Anchor Arrangement(take the construction order from the top to the bottom as example). The following various construction work shall be carried out timely.（2） 、施工準(zhǔn)備2. Construction Preparation、錨桿的簡(jiǎn)述 Brief Introduction of Anchor、錨桿長(zhǎng)度：～，錨桿錨固長(zhǎng)度5～8m,。錨具（M173,3孔）≥設(shè)計(jì)值380KN，與鋼絞線(xiàn)3162。Reserve anchor working area(500mm below anchoring point) while excavating or backfilling of earthwork. Airdriven downhole hammer construction technology shall be adopted for prestressed anchor whose length is 1520m and anchorage length is about 58m.、風(fēng)動(dòng)潛孔錘施工方法 . Airdriven Downhole Hammer Construction Method 、根據(jù)設(shè)計(jì)圖紙要求，測(cè)量人員測(cè)定錨桿孔的孔位，打入標(biāo)樁，注明錨孔編號(hào)（詳見(jiàn)附圖一、二、三）。松散土層及破碎巖石中采用低轉(zhuǎn)數(shù)，完整基巖中鉆孔中適當(dāng)提高轉(zhuǎn)數(shù)。對(duì)測(cè)放并驗(yàn)收合格的錨孔位置進(jìn)行編號(hào)，并用油漆標(biāo)示在現(xiàn)場(chǎng)坡面上，該編號(hào)作為錨桿制作編號(hào)的依據(jù)。當(dāng)錨孔深度已滿(mǎn)足要求，則以高壓風(fēng)吹凈，直至吹出清水。Drilling diameter and depth shall not less than designed valu
